The Saucer Life is a sane, straight forward look at the
phenomena from a well versed student of the field, and well worth the time.
The recommendations here are interesting, not what one might expect. The recommendation of Jim Moseley's book is one I would heartily endorse, a wildly humorous look at the personalities in the American saucer scene as it was emerging in the middle of the last century, a field that Jim himself referred to as UFO-ology, or rather, U-Fool-Ogy.
Keep up the great work, Professor Gulyas!
